I'm hope I can use the AD5270 or AD7272 as a replacement for as 10 Kohm (25 degres celcius) NTC resistor.
I would like to connect the AD5270/AD5272 to an Arduino-board (ATMEGA328). Does somebody have a diagram/Sketch for the connections?
The controller for my wood pellets burner has temperature inputs for inside and outside temperature.
The inputs are for NTC resistors (10 Kohm at 25 degres celcius).
I'm hoping to connect a AD5270 or AD7272 to the controller in stead of the NTC.
I will then write a program for an arduino that, by controlling the AD5270 or AD7272, can tell the controller the outside temperatue using i.e. this
as a wireless temperature sensor transmitter
as a reciever controlling the AD5270 or AD7272
I hope it makes sense
hey! sorry to bring this thread back from the grave, but im doing the exact same thing.
difference begin im using a ESP32 and its out-of-the-box connectivity features.
how did it go in your case Wolle?
im finding it troublesome to emulate the NTC in a reliable fashion...
Could you share the schematic of how the connections are made in your case?
im using MCP42010 / MCP42100 digipots and a ESP32 Devkit v4
